So.. teaching children that fish and squids swim and dive and birds fly is not really true, is it?
It all starts with a picture on fb and this message: "Polluted oceans cause squid to grow lungs and develop the ability to fly" http://9gag.com/gag/342697 It now has 47.501 likes and 6.327 shares and also, this description: "On the contrary, I think science would have a field day with it!".
So, what do I do? :D google it like all human beings would do.
And what do I find out?
That Squids look so beautiful in the pictures taken and it's a marine science article in a nice journal to see for yourself: http://link.springer.com/content/pdf/10.1007%2Fs00227-013-2169-9.pdf
Another source of info about Japanise Flying Squinds might be this http://www.dailymail.co.uk/sciencetech/article-1338220/Graham-Ekins-Japanese-squid-photos-leap-air-dodge-predators.html where it says that "The flying squid swim in shoals and leap from the surface of the water and are often mistaken for the more common flying fish.

This part is even better: "For years, fishermen and sailors reported seeing squid “flying” across the surface of the sea but no one had taken photographs of the squids in action." (see the link http://www.calacademy.org/sciencetoday/the-flying-squid/5510326/)
Some Squids do fly. Also, there is a fish family called the Exocoetidae that flies. Takning about cattegories: Higher classification: Beloniformes and Lower classifications: Hirundichthys, Cypselurus, Cheilopogon By now, with the Life of Pi movie, I guess that you know about category of flying fish. http://en.wikipedia.org/wiki/Flying_fish
This also happens - http://www.newscientist.com/blogs/shortsharpscience/2012/05/bioluminescent-bloom-makes-bea.html
Therefore, some fish do fly and squids use jet propulsion to fly. Jellyfish can light waters and this is something you should search for yourself.
